ZLAN6042/ ZLAN6002/ ZLAN6032 topview as Figure 1 and Figure 3. ZLAN6042/ ZLAN6002/ ZLAN6032 have slide rail slot on the bottom. It can be mounted on slide rail easily.
Panal led:
1.ACT: When this light is blue, it indicates data is communidate between Ethernet and ZLAN6042/SLAN6032.
2.LINK: When this light is green, it indicates the RJ45 netline is pluged in. When this light is blue, it indicates the TCP connection is established.
3.POWER: When this light is on, power is supplied.
ZLAN6042/ ZLAN6002/ ZLAN6032 one side is defined as:

Note:
1. If the type is ZLAN6002, The RJ45 is RS485 input, and 485A and 485B corrosponeding to RJ45 pin 1 and pin 2.
2. There are different type of sub-type for different AI input format. The default sub type is”-V5”.
l ZLAN6042-V5, ZLAN6032-V5, ZLAN6002-V5: Votage input 0~5V;
l ZLAN6042-V10, ZLAN6032-V10, ZLAN6002-V10: Votage input 0~10V.
l ZLAN6042-I20, ZLAN6032-I20, ZLAN6002-I20: Current input 0~20mA.
l ZLAN6042-R10K, ZLAN6032-R10K,ZLAN6002-R10K: resistor input 0~10K.
ZLAN6042/ ZLAN6002/ ZLAN6032 is designed based on Modubs TCP and Modubs RTU, the command and register defined as follow:
